' WILLIAM K. CARNES, or McKEES ROCKS, PENNSYLVANIA. I

SHEARING-MACHIN E.

Application filed June 15, 1912, Serial No. 703,823.

To all whom it may concern Be it known that I, WILLIAM K. CARNES, a citizen of the United States, residing at Mo- Kees Rocks, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Shearing- Machines, of which'the following is a specification.

This invention relates to improvements in shearing machines'and has for itsobject to provide a means for shearing or slicing sections from rounds or cylindrical metal billets.

The principal object of the invention is to provide a means for shearing sections from cylindrical billets whereby clean cuts or cuts free of corrugations may be had.

Another object of the invention is to provide a traveling shear for operation on a fixed member to be sheared.

With the above and other objects in view, which will be more fully set forth in the following specification, I have invented the device illustrated in the accompanying drawings in which 7 Figure 1 is a top plan view of my improved shearing device, Fig.2 is a side elevation thereof, Fig. 3 is a view taken on line AA of Fig. 1, partly in section and partly in elevation, Fig. 4 is a sectional view taken on line BB of Fig. 5, and Fig. 5 is a front.

elevational view. 1

Like reference characters indicate like parts throughout the specification and in the several views in the drawings in which 1 and 2. are roller supporting frames upon which the rollers 3 are mounted upon which a steel or iron billet 4. travels to the shearing device 5, first passing between the clampin device 6. The rollers 3 have bevel gears on their shafts 8 which mesh with the gears 9 on the shaft 10 whereby the rollers are rotated.

The clamping device 6 consists of an adjustable stationary jaw 11 having a guide member 12 thereon for directing thebillet 4, and a movable jaw 13 mounted on a rod 14 with a piston 15 on its end operating'in the cylinder 16 whereby said jaw may be operatedeither by compressed air, steam or other Specification of Letters Patent.

fluid, whereby the clamp may be very rap-- idly operated. The jaw 11 is mounted on a screw-shaft 17 operating in the bearing. 18 and is adjusted by the jam nuts 19 and 20.

The shearing device 5 is constructed in the following manner. A fixed frame 21 having a stationary gear or rack 22 thereon, has rotatably mounted thereon a revolving drum 23 which is provided with a circular gear or rack 24 and which travels therewith. A gear wheel 25. driven bya shaft 26 and meshrack and the drum 23. The member 21 is provided with a circular track 27 in which members 28 on the drum. 23 travel; The

'ing with, the rack 24 is adapted to rotate said V drum 23 is provided with a pair of opposing openings .29 and 30 through which screw shafts 31 and 32 operate. Mounted in said drum and on said screw shafts are bearing members 33 and 34, on which are rotatably mounted the shafts 35 and 36 which carry the revolving shears 37 and 38. On the periphery of saiddrum 23 are worm wheels 39 and 40 which are fixed to the internally screw-threaded collars 41- and 42 on the shafts 31 and 32-, and mounted on said drum are worm shafts 43 and 44 which carry pinions 45 and 46 which mesh with the rack 22 whereby said worms are operated, and which in turn operate thev worm wheels 39 and 40 whereby the collars 41 and 42 are rotated to gradually drive inwardly the shafts 31 and 32 causing the shears to be driven in upon the billet 4.

When the drum 23 is operated in an op-- posite direction the pinions 45'and 46, worms 43 and 44,.gears 39 and 40 and shafts 31 and 32 are consequently rotated in an-opposite direction thereby drawing outwardly said shafts 31 and 32 and bring said shears 37 and 38 away from the path of the billet 4; thus a reciprocating movement'is imparted to said shafts and shears caused by the forward and backward rotation of the drum 23.

Having now described my'invention that which I claim to be new and cure by Letters Patent is: p

1. The described device consisting of a fixed base having an integral drum, a cylindrical drum rotatably mounted thereon, cendesire to 1 protrally projecting shears mounted within said rotatable drum, rollers adapted to feed a billet to said shears, a hydraulic clamp adapted to hold said billet between said shears.

2. The described device consisting of a fixed base having an integral drum, a cylindrical drum rotatably mounted thereon, centrally projecting shears mounted within said rotatable drum, rollers adapted to feed a billet to said shears, a hydraulic clamp adapted to hold said billet between said shears, andv screw bearings projecting through said rotatable drum upon which said shears are mounted, means for reciprocating said screws.
